There's no way to select any particular area to stabilize, although that might be a good thing to request using
Rate Us & Provide Suggestions under PD's
File menu.
You may have some luck by experimenting with different combinations of the motion level slider and enabling/disabling rotational shake and enhanced stabilizer, but if you have a tool that already does what you want, it seems like using that and importing the result into PD would be the quickest way to go.
